trying to clarify initrd vs initramfs vs neither

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  i'm reading the code under init/ and checking "make menuconfig" to
clarify what choices you have in building in support for
initrd/initramfs.  as in, if you do "make menuconfig", under "General
features," you see a single selection to choose whether you want *any*
of that support (that would be the BLK_DEV_INITRD config variable).

  but having used initrd for years and now switching to initramfs, is
it not technically possible to have one without the other?  i'm just
trying to figure out whether the logic used for those features in the
Kconfig files and Makefiles actually makes sense.

  should i not be able to say i want initrd support without needing
initramfs?  or perhaps the reverse?  i'm just starting to look at the
code so it might become obvious shortly.  but does anyone else think
that maybe that Kconfig and Makefile content can be simplified?
